Project: Entity Embed [1]
Date: 2021-September-15
Security risk: *Moderately critical* 11∕25
AC:Basic/A:User/CI:None/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross Site Request Forgery

CVE IDs: CVE-2020-13673
Description: 
This advisory addresses a similar issue to Drupal core - Moderately critical
- Cross Site Request Forgery - SA-CORE-2021-006 [3].

The Entity Embed module provides a filter to allow embedding entities in
content fields. In certain circumstances, the filter could allow an
unprivileged user to inject HTML into a page when it is accessed by a trusted
user with permission to embed entities. In some cases, this could lead to
cross-site scripting.

Solution: 
Install the latest version:

  * If you use the Entity Embed module for Drupal 8 or 9, upgrade to Entity
    Embed 8.x-1.2 [4].

Drupal 7 versions of Entity Embed do not have a stable release and therefore
do not receive security coverage.
